We study the behavior of orbits in two different galactic dynamical models,describing the motion in the central parts of a triaxial elliptical galaxy with a dense nucleus.Numerical experiments show that both models display regular motion together with extended chaotic regions.A detailed investigation of...

TOPOLOGY AND PERIODIC ORBITS OF RING-SHAPED POTENTIALS AS A GENERALIZED 4-D ISOTROPIC OSCILLATOR In this work we study a generalized integrable biparametric family of 4-D isotropic oscillators. This family allows to treat, in a unified way, oscillators... MC Balsas,S Ferrer,E. S.jimnez,.....
At different times of the year, different constellations of stars dominate the night sky as the Earth orbits the Sun. Ancient people must have recognized this fact and constructed sidereal calendars based on the movement of the stars, as did the ancient Egyptians, Greeks, and Babylonians. ...

In an extensive memoir-almost a complete treatise--on "Dynamical Systems with Two Degrees of Freedom" (Trans. Amer. Math. Soc., 18 ; 1917), he reduced all problems relating to such systems, even in the 'irreversible' case, to the problem of determining the orbits of a particle ...
has the advantage of reducing the number of degrees of freedom required to describe the dynamics of the fault; furthermore, it allows the study of the evolution of the system by means of orbits in the phase space, making it possible to better visualize the different aspects of the dynamics....
【题目】When early colonial settlers went to America, they took many forms of dance to their new home. Square dancing, one of the oldest forms of American folk dancing, developed from several different Old World group dances, mainly English country dances, and the French quadrille(四对方舞)....
